Abstract
The utility model discloses a switch with an electric power storage function and a power loss alarm function. The switch comprises a case; a switching unit and an electric power storage unit, which are used for normal work of the switch, are disposed in the case; the switching unit is connected with the electric power storage unit through a change-over switch; the case is provided with a power interface; the switching unit and the electric power storage unit are connected with the power interface; the power interface is connected with an external power supply; and a power loss alarm module is also arranged in the case and is connected with the switching unit. The novel switch has certain endurance capability; in case of sudden power failure, the electric power storage unit can be enabled timely to provide electric power for the switch and a power loss alarm signal is output; when the external power supply works normally, the electric power storage unit is in a standby state and is charged all the time and the switch obtains the electric power from the external power source directly. Therefore, the influence brought forth by instant interruption of communication data caused by sudden power failure can be removed.
Description
Technical field
The utility model relates to a kind of switch, relates in particular to a kind of switch with electric power storage and dead electricity alarm function.
Background technology
Current switch need to switch on power and could normally work, once power-off cannot continue to use.Particularly, for the industrial system of a large amount of dependence transfer of data, in the time that generation special circumstances cause power failure, the instantaneous interruption of transfer of data will cause unpredictalbe economic loss, have a strong impact on the development of industrial system.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of switch with electric power storage and dead electricity alarm function.
For achieving the above object, a kind of switch with electric power storage and dead electricity alarm function described in the utility model, comprise cabinet, be provided with the crosspoint and the electricity accumulating unit that carry out the normal work of switch in described cabinet, described crosspoint is connected by a change over switch with electricity accumulating unit; On described cabinet, be also provided with power interface, described crosspoint is all connected with power interface with electricity accumulating unit; Described power interface is connected with external power source; In described cabinet, be also provided with a dead electricity alarm module, described dead electricity alarm module is connected with crosspoint.
The beneficial effects of the utility model are:
The utility model provides a kind of novel switch, has certain flying power, and in the time of suddenly power down, can enable in time electricity accumulating unit and provide electric power for switch, and output dead electricity alarm signal.In the normal situation of outside power work, electricity accumulating unit is in stand-by state and charging always, and switch directly obtains electric power from external power source, has solved the impact that burst power failure causes the instantaneous terminal of communication data to cause.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of switch described in the utility model embodiment.
Embodiment
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, a kind of switch with electric power storage and dead electricity alarm function described in the utility model embodiment, comprise cabinet, be provided with the crosspoint and the electricity accumulating unit that carry out the normal work of switch in described cabinet, described crosspoint is connected by a change over switch with electricity accumulating unit; On described cabinet, be also provided with power interface, described crosspoint is all connected with power interface with electricity accumulating unit; Described power interface is connected with external power source; In described cabinet, be also provided with a dead electricity alarm module, described dead electricity alarm module is connected with crosspoint.
When use, can use power line with attaching plug, power interface to be connected with external power source.Having under electric state, external power source is electricity accumulating unit charging in to crosspoint power supply, and when power-off, electricity accumulating unit for crosspoint power supply, is avoided can not using because power-off causes switch in time.One end of dead electricity alarm module connects the input/output end port of crosspoint, and the other end is connected to the alarm signal output ends mouth that is arranged at casing.In the time that crosspoint monitors the outside civil power loss of switch, control the closure of change over switch, and alarm signal is gone out by the cable transmission being connected with alarm output signal, make operating personnel find in time switch dead electricity situation.
The utility model provides a kind of novel switch, has certain flying power, and in the time of suddenly power down, can enable in time electricity accumulating unit and provide electric power for switch, and output dead electricity alarm signal.In the normal situation of outside power work, electricity accumulating unit is in stand-by state and charging always, and switch directly obtains electric power from external power source, has solved the impact that burst power failure causes the instantaneous terminal of communication data to cause.
Above; it is only preferred embodiment of the present utility model; but protection range of the present utility model is not limited to this; any be familiar with those skilled in the art the utility model disclose technical scope in; the variation that can expect easily or replacement, within all should being encompassed in protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claim was defined.
